Silt Layers and Water Well Drilling Rig
-
Impact rigs in silt: They break silt via repeated bit impacts, piercing small hard layers. Useful for such mixed silt conditions.
-
Ensuring wall stability: Silt loosens easily when shocked, risking collapse. Use high-viscosity, thixotropic mud. Add clay to boost support; it gels quickly when static.
-
Controlling impact and maintaining bits: Keep frequency at 30-40 times/min, stroke 0.5-1m. Clear slag after each impact. Check bits often; repair or replace worn ones. Reinforce walls in thick silt.
Experienced operation makes the water well drilling rig work in silt. The water well rig succeeds with precise control here.
